2. Description of the Related Art For example, when sterilizing pool water,
May be performed using ozone. For example, there is one as shown in FIG. First, there is a pool 301 to which a pool water circulation circuit 303 is connected. This pool water circulation circuit 3
03 is provided with a circulating water pump 305, a filter 307, a heat exchanger 309, and a hair collector 311. Further, a sterilization circuit 313 is branched and connected to the pool water circulation circuit 303.

The sterilization circuit 313 has an on-off valve 315,
An ejector 317, a gas / liquid separation tank 319, and an on-off valve 321 are sequentially inserted. An ozone tube 323 is connected to the ejector 317.
The ozone generator 325 and the compressor 327 are connected to 23. Further, an exhaust ozonolysis tower 329 is connected to the gas / liquid separation tank 319.

According to the above configuration, pool water is constantly circulated and supplied to the pool 301 by the pool water circulation circuit 303. Ozone is sucked through the ozone tube 323 by the negative pressure suction action of the ejector 317 (sucked into the water passing through the ejector 317), and is supplied as it is into the pool water circulation circuit 303.

A plurality of (eight in this embodiment) cutouts 147 are formed in the annular bottom 143 at equal intervals in the circumferential direction. The plurality of cutouts 147 form a vane structure. Then, the ozone water mixed with gas and liquid is finally pressurized and discharged by the turbo vane 97 having such a configuration. Further, a pressurizing chamber 98 is provided between the turbo vane 97 and the flange 69 so that the pressurized air
The liquid mixture fluid is pressurized here and promotes the dissolution of the ozone crushed bubbles into the water 4 to be treated.

The operation will be described based on the above configuration. When the drive motor 83 is activated and rotated, the shaft 81 rotates in the same direction, whereby the impeller 91 and the turbo runner 95 fixed to the shaft 81 rotate. Then, the treatment target water 4 in the water tank 3 is sucked through the tube 10 and the ejector 75. This water to be treated 4
Generates a negative pressure when passing through the ejector 75, and ozone is sucked through the tube 12 by an ejector action using the negative pressure. Then, the gas / liquid mixed fluid of the water 4 to be treated and ozone flows into the casing 57 through the inflow port 73 of the casing 57. The gas-liquid mixed fluid decompresses and expands when it flows into the casing 57, and the expansion causes ozone bubbles to expand.

An impeller 91 is disposed inside the inflow port 73 of the casing 57, and the water 4 and the ozone to be treated are sucked and pressurized through the plurality of recesses 113 of the impeller 91. Is done. At the same time, a baffle piece 125 is disposed at an outer peripheral position of the impeller 91, and an inner peripheral surface of the upright portion 129 of the baffle piece 125 and an outer peripheral surface of the impeller 91 are disposed with a slight gap. ing. Then, as the impeller 91 rotates, the outer peripheral surface of the impeller 91 and the inner peripheral surface of the upright portion 129 of the baffle piece 125 perform an action of "cutting" the suctioned water 4 and ozone, and As a result, ozone contained in the form of bubbles is crushed (action of breaking bubbles). The crushed ozone is dissolved in the water 4 to be treated.

Then, the water 4 to be treated, in which the bubble ozone has been crushed, is sucked into the turbo suction 93 through the notch 123 of the turbo suction 93. The water to be treated 4 sucked into the turbo suction 93 is further reduced by the action of the plurality of recesses 121 of the turbo suction 93 and the plurality of notches 139 of the turbo runner 95 opposed to the turbo suction 93. The bubbles will be crushed.

The water 4 to be treated in which the ozone bubbles are crushed by the turbo suction 93 and the turbo runner 95 described above.
Is discharged to the turbo vane 97 side, and the turbo vane 97
Is pressurized by the pressurizing action in the pressurizing chamber 98. At the same time, the above-mentioned pressurization promotes the dissolution of the ozone crushed bubbles in the water 4 to be treated. The water 4 to be treated pressurized by the turbo vanes 97 is discharged into the pressurizing chamber 98 between the turbo vanes 97 and the flange 69, and is discharged as ozone water through the outlet port 77 of the flange 69 and the ozone water discharge pipe 13. Will be done.

According to this embodiment, the following effects can be obtained. First, it is possible to efficiently dissolve ozone, which was conventionally difficult to dissolve in the water to be treated. Specifically, first, the casing 6 passes through the ejector 75 and
When the air is sucked into the space 3, the air is decompressed and expanded, and the expansion expands ozone bubbles. In that state,
The impeller 91 and the baffle piece 125 have a function of breaking air bubbles. That is, the bubbles of ozone are once expanded to expand the air bubbles, and are efficiently crushed by the next crushing operation. The turbo suction 93 and the turbo runner 95 performed next also have the effect of breaking air bubbles of ozone. The ozone bubbles sucked by the action up to this point are efficiently crushed. And finally, it is pressurized by being pressurized by the turbo vane 97 and also the pressurizing chamber 98.
The ozone crushed in the inside efficiently dissolves in the water 4 to be treated, and as a result, the dissolution rate of ozone can be increased.

As described above, ozone can be efficiently and reliably dissolved in the water 4 to be treated. Therefore, a gas / liquid separation tank, a waste ozone decomposing tower, etc., which are conventionally used, can be used to dissolve ozone in the water to be treated. It is no longer necessary to treat a large amount of ozone that was not present, so that the equipment can be simplified and the cost can be reduced. In addition, even in the case of a pool water sterilizer, the generated ozone is surely dissolved in the water to be treated, so that the required amount of ozone generation is smaller than before, and the ozone generator itself can be used. The ability is small. This has also made it possible to reduce the size and cost of the equipment.

5. The impeller 163 rotates. And tube 10
Then, the processing target water 4 in the water tank 3 is sucked through the ejector 75. A negative pressure is generated when the water to be treated 4 passes through the ejector 75, and ozone is sucked through the tube 12 by an ejector action using the negative pressure. Then, a gas / liquid mixed fluid of the water 4 to be treated and ozone flows into the decompression chamber 225 in the casing 57 via the inflow port 73 of the casing 57. The gas-liquid mixed fluid of the treatment target water 4 and ozone that has flowed into the decompression chamber 225 is decompressed, and the ozone bubbles expand.

This acts to "cut" the expanded ozone bubbles, thereby crushing the expanded ozone bubbles. At this stage, the dissolution of ozone in the water 4 to be treated is promoted. Next, turbo runner 1
The gas-liquid mixed fluid flowing out to the secondary side of 55 is pressurized by the action of the baffle piece 157 attached to the stage partition plate 161. The pressurized gas-liquid mixed fluid is sucked by the impeller 163, further pressurized in combination with the pressurizing action of the baffle piece 165 disposed on the secondary side, and flows out into the pressurizing chamber 227. .

In the gas-liquid mixed fluid flowing into the pressurizing chamber 227, the ozone remaining in the bubble state is further dissolved in the water 4 to be treated. Then, the water is discharged as ozone water through the outflow port 77 of the flange 69 and the ozone water discharge pipe 13. FIG. 29
The flow path of the gas-liquid mixed fluid is shown by arrows in FIG. In the case of this embodiment, the dissolution rate of ozone can be increased more than in the case of the first embodiment. This is first of all, the decompression chamber 225
This is because, by providing the air-liquid mixture, the introduced gas-liquid mixed fluid is positively decompressed and expanded, and the bubble-like ozone is effectively expanded. In addition, the expanded ozone bubbles are separated into respective notches 175 by the relative rotation of the mixing vane 151, the turbo vane 153, and the turbo runner 155.
Since it is crushed by 179 and 189,
This is because crushing can be performed more efficiently. In addition, the provision of the two baffle pieces 157 and 167 contributes greatly, not only to the effect of crushing bubbles, but also to promote the pressurization and increase the pressure in the pressurizing chamber 22.
